Hi! Does Mini-Agent have plans to support streaming output for LLM responses?
Thanks!

This PR #81 implements streaming output rendering for the CLI. It adds a StreamingRenderer class that follows the stable prefix + unstable suffix pattern to reduce visual flicker during long-running commands.

The implementation addresses the streaming output request in this issue.
